Aug.18 (GMM) Even with Renault's Valencia race ban now overturned, Romain Grosjean late on Monday was still not ready to confirm that he will contest the European grand prix for the French team.

With Nelson Piquet having already announced that he has been ousted, we revealed on Monday that if Enstone based Renault was pardoned by the Court of Appeal, an announcement about Renault's driver lineup would be made early on Tuesday.

French-Swiss reserve and GP2 driver Grosjean, 23, is first in line for the seat alongside Fernando Alonso, but he told the Tribune de Geneve newspaper: "As long as there's nothing official, nothing is for certain."
